Pat Symonds has left Williams according to a report by Autosport magazine.
The 63-year-old only joined the team in 2013 but speculation surrounding whether he was to retire at the end of the 2016 season has been rife for quite some time.
Symonds, who moved to the team following a stint with what is now Manor, oversaw the team's return to the front, with Williams finishing third in both 2014 and 2015, and fifth this year after a decade of struggles.
He was banned from being involved in F1 following the revelation of the scam, only for his ban to later be overturned.
